Application filed May 16, 1912. Serial No. 697,735.

To all rr/wm it may concern.

Be it known that I, MICHEL J. SELZER, a citizen of the llnited States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements iii lVheel-Rims; and I do declare the following to be a full, clear, and exact description of the invention, such asqvill enablexothers skilled in the art tio which vit/i appertains to make and use the same." A

This inv'htion relates t improvements in means for'l l detachably securing tires to vehicle wheels and is especially designed for pneumatic and cushion tires.

The dbject of the invention is to provide simple and efficient means for i'eliably lockl iiiga tire in operative position and which may be readily and quickly applied and removed especially adapting the device for use on motor vehicles.

Another object of the invention is to prof rvide a peci'iliarly constructed locking ring and rim for cooperating with each other to secure the tire in position.

lfVith these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts, as will be hereinafter nioi'e `fully described and claimed.

In the accompanying drawings Figure 1 represents a detail perspective sectional view of one form of the invention applied to a solid cushion tire; Fig. 2 is aside elevation of one of the bolts Afor securingthe locking Fig. 3 is a detail perspective sectional view of a slightly different form or application of the invention to a solid cushion tire. Fig. 4 is a similar view of an'- other form detached. Fig. 5 is a detail perspective'isectional view of another form of the invention applied to a pneumatic tire.

In the', embodiment illustrated in Fig. l

the simplest form of the invention is; shown in which 'a rim lconstructed in accordance with thisfkinvention `is`-nsed 1n connection with a solid rubber cushion tire without the use of any clenchei' rings. This rim 1 has one edge turned up to foi-insa clencher flange 2 and the other side edge isinclined downwardly and outwardly and then tii'rned upwardly to form a seat 3 and clenchn` flange 4 for a locking ring This locking ring 5 which constitutes one of the essential features of the invention is here shown coinposed of twosections each having a phiprovided with the usual nut 8 with which is i engaged a retaining spring 9. This retaining spring is preferably constructed 0f bl'lSS wire to prevent corrosion and the helixr 10 thereof is held in fixed position on the rim l by a rivet 11. The arms 12 of this spring engage the opposite faces of the nut 8 and hold it against' turning. The solid rubber tire A is of usual construction with grooves B in its opposite sides near its base for engagement by the riin lianges, the flange 2 being here shown engaged with one groove and the locking ring. 5 with the other. This ring 5 is here shown substantially dianiond-shaped in cross section one edge 5 thereof being elongated and engaged with the book-shaped rIencher-like flange 4 of the riin while its diametrically opposite edge engages the groove in the .tire A.

The bolts (f3 are passed transversely tl'irough this ring substantially midway of the width thereof and when the nuts are screwed tight the bolts draw the ring down into close engagement with the tire and rim as shown in Fig. l.-

As clearly shown in the drawings all the inodilications of the. invention contain la wheel rim carrying on one edge some means for engagement with one side of a resilient tire and on its other edge a downwardly or inwardly inclined portion terminating in an annular seat which is curved or rounded in cross section, said seat being formed by upturning said edge of the rim. All forms also contain a ring-like locking ineinbci" composed ol" one or more parts andnhaving its outer edge rounded to rock in said curved 'iat while its upper and inner odge is shaped to coact with tho other side of the tire to retain the same in position on the rim.

In Fig. 3 a slightly different form of the invention is shown in which clenoher rings 13 are shown in connection with the saine foiin of rim and locking ring described above. The tire is of slightly different foizin and in applying it the tire is slipped on tl'esijiin simultaneously with the clcncher rings ]..f"tl-ie locking ring 5 is then inserted as shown witlr-oiio edge engaging the hook-
